[Refresh rate of Vive Tracker 3.0]

I have the same issue. I'm using the SteamVR null driver and I have the tracker working in Unity using the SteamVR plugin, but I'm only getting about 30 Hz updates.

[How to use Ultimate Tracker]

(If my previous post with error messages goes through) I was able to fix it, I changed:

HTCViveTrackerProfile.cs
// line ~14
// Comment out:
//using PoseControl = UnityEngine.XR.OpenXR.Input.PoseControl;
// Change to:
using PoseControl = UnityEngine.InputSystem.XR.PoseControl;

Unity deprecated UnityEngine.XR.OpenXR.Input.PoseControl (it says so if you mouse over it in Visual Studio), they suggest UnityEngine.InputSystem.XR.PoseControl instead.

Now I just need to keep something on my Oculus Quest 2's sensor to make it think a user is in the headset, and I receive tracking in Unity. Trying to figure out if I can eliminated the headset now.

[How to use Ultimate Tracker]

Managed to get the trackers somewhat working in PC VR.

I've joined the discord (https://discord.gg/viverse) to get access to the beta.

I installed the Vive Streaming Hub (https://www.vive.com/us/support/vs/category_howto/using-vive-streaming.html).

Paired & calibrated the tracker with the help of an Oculus Quest 2. Assigned the tracker as Camera in SteamVR.

I logged in & followed the VIVE_Ultimate_Tracker_PC_OpenXR_v2.pdf, however, it is not working. I'm on Unity 2022.3.16, URP, OpenXR Plugin + Vive OpenXR.

Added the HTC VIVE Tracker Profile C# script to the project:

Created an Input Action asset and assigned the camera tracker:

I get a warning:

No GetDeviceLayoutName() override detected in HTC Vive Tracker Profile. Binding path validator for this interaction profile is not as effective. To fix, add GetDeviceLayoutName and GetInteractionProfileType override in this profile.

I was able to get the tracker working in Unity with the SteamVR plugin, but I'd vastly prefer using OpenXR.

[How to use Ultimate Tracker]

Is there really no way to use this without a headset?

I'm trying to use the Vive Ultimate Tracker has a general purpose 3D tracker as a Windows application.

If not I'm going to have to return it.
